Product Features
1. 180° -Wide Opening for Maximised Space Utilisation
The 180 Degree Concealed Hinge overcomes traditional hinge limitations, enabling door panels to swing fully open to 180°. This prevents door obstruction in passageways, proving particularly suitable for narrow corridors or scenarios requiring large-item handling (e.g., warehouses, laboratories). The dual-axis linkage mechanism ensures smooth, snag-free operation. Paired with 304 stainless steel pivot points, it maintains precise opening angles over extended use, minimising friction-induced deviation.
2. Three-dimensional adjustment for precise correction of installation errors
The product incorporates built-in X/Y/Z three-way adjustment mechanisms, enabling independent fine-tuning vertically (up/down), horizontally (left/right), and in depth (forward/backward). With an adjustment range of ±3mm, it swiftly corrects issues such as poor door closure caused by uneven walls, warped door frames, or installation errors. Adjustments require no door disassembly, being completed solely with a hex key. This proves particularly suitable for refurbishment projects or high-precision commercial settings, significantly reducing rework rates and time costs.
3. 200,000-cycle durability for high-frequency use
Passed EN 1395 standard testing for 200,000 opening/closing cycles, simulating high-frequency scenarios (e.g., hospitals, shopping centres) with 500 daily operations while maintaining smooth rotation and silent operation. The zinc alloy body undergoes T5 heat treatment for reinforcement, enhancing impact resistance and fatigue resistance by 40%. An anodised anti-corrosion coating protects surfaces, ensuring long-term reliability in humid environments or coastal regions. Its lifespan exceeds that of standard hinges by more than double.
4. 132-minute fire resistance for critical safety protection
Compliant with EN 1634-1 fire resistance standards, the hinge structure remains intact without deformation after 132 minutes of exposure to high-temperature flames and radiant heat, ensuring fire doors maintain their barrier function. Concealed design eliminates the risk of exposed metal components softening and detaching under extreme heat. Combined with a T-shaped anti-pry groove, security is enhanced by 30%, buying critical time for evacuation and firefighting operations.
5. Concealed Aesthetics: The Minimalist Design Choice
The 180 Degree Concealed Hinge employs flush mounting, where the hinge is entirely concealed within the door frame when the door is closed, leaving only a 1mm gap. This creates a visually seamless, ‘hardware-free’ minimalist effect. Compared to exposed hinges, it avoids visible screws and metal components that compromise the door's integrity. Suited to modern minimalist and industrial design aesthetics, it elevates spatial sophistication and brand identity.
Suitable Applications
1. High-traffic commercial premises
In environments like shopping centres, office buildings, and hotels where doors open and close over 300 times daily, hinges must offer exceptional durability and rapid adjustment capabilities. The 180 Degree Concealed Hinge's 200,000-cycle testing and three-dimensional adjustment ensure long-term stable operation, minimising safety risks from sagging or improperly sealed doors. Its concealed design also enhances the aesthetic appeal of public spaces.
2. Fire-Critical Public Buildings
Facilities like hospitals, schools, and airports demand hinges certified to EN 1634-1 for exceptional fire resistance and structural integrity. This product delivers 132 minutes of fire performance alongside a TU-type anti-pry groove design, maintaining compartmentalisation during fires to secure vital evacuation time. It fully complies with mandatory requirements for fire door hardware under the Building Design Fire Protection Code.
3. Humid or Corrosive Environments
In coastal regions, laboratories, industrial plants, and other settings prone to salt spray or moisture corrosion, hinges must offer corrosion resistance. The zinc alloy body undergoes anodised treatment, paired with 304 stainless steel pivot pins, effectively combating rust caused by damp conditions. This extends product lifespan and reduces long-term maintenance costs.
4. Premium Residential & Bespoke Interiors
High-end residential projects prioritising minimalist aesthetics and precise adjustment require concealed installation and three-dimensional adjustment capabilities. The 180 Degree Concealed Hinge's 1mm ultra-narrow gap and 180° swing design achieve seamless integration between door and wall, complementing modern minimalist and wabi-sabi styles to elevate spatial sophistication.
5. Narrow Passages and Complex Layouts
Corridors, lift lobbies, and plant rooms demanding maximum space utilisation require hinges supporting 180° swing operation. This product prevents door obstruction in passageways, facilitating movement of bulky items (e.g., medical equipment, furniture). Its three-dimensional adjustment capability corrects installation inaccuracies caused by confined spaces, ensuring long-term stable door operation.
